Sagot :

Answer:

Problem #1 : 21.2 %

Problem #2 : 20g of glucose

Explanation:

Problem 1: mass solution = mass solute + mass solvent

mass solution = 5.30 g + 19.7 g

mass solution = 25.0 g

percent by mass = (mass solute / mass solution) × 100

percent by mass = (5.30 g / 25.0 g) × 100

percent by mass = 21.2%

Problem #2 :

xg / 400 = 0.05g / m * L

xg = (400mL)(0.05g / m * L)

x g = (400ml)(5g / 100mL)

x = 20g

xg / 400 = 0.05g / m * L

xg = (400mL)(0.05g / m * L)

x g = (400ml)(5g / 100mL)

x = 20g
